Effects of dietary supplementation on vegetation cover and its defoliation by sheep in extensive husbandry
(Elsevier, 2022-06-06)Dietary supplementation is one of the most used strategies to reduce the effect of environmental fluctuations in arid and semi-arid environments. We evaluated changes in vegetation and in patterns of animal defoliation as ... -
How does grazing affect soil water availability in the Patagonian steppe?
(Elsevier, 2022-06-01)In the Patagonian steppe, grazing may or may not reduce soil water availability: it may increase evaporative losses, because it reduces plant cover, but may decrease transpiration losses because it decreases plant biomass. ... -
Impact of ponderosa pine afforestations on soil organic matter (SOM) in semiarid steppes of western Patagonia, Argentina
(2017-10)The western steppe of Patagonia, Argentina, is being afforested with conifers since long ago. However, the effects of this land-use change on some soil parameters are still unknown. We determined soil organic matter (SOM) ... -
Impacto de la redistribución de agua en áreas de estepa: estudio de caso en un arroyo temporario del NO de Chubut = Water redistribution effect in steppe areas: a study case in a temporary stream of the Chubut NW
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2013)Con el objetivo de evaluar el impacto en la vegetación y el suelo de una obra de redistribución de agua en área de estepa, se desarrolló durante 2010 y 2011 un ensayo en el área ecológica de Sierras y Mesetas Occidentales ... -
Phenotypic plasticity in leaf traits in response to experimental precipitation increase: wettability, foliar water uptake and gas exchange
(Wiley, 2023-07-12)Water availability is one of the factors affecting plant growth and development, especially in arid and semiarid environments. Changes in precipitation due climate change alter water availability to plants impacting on ... -
Trends of aboveground net primary productivity of Patagonian meadows, the omitted ecosystem in desertification studies
(MDPI, 2023-05-08)The United Nations defines desertification as the loss of productivity in arid and semiarid environments. The extended steppes of Patagonia harbor small meadows whose compounded area is comparatively small, but their ...
